I drained the oil in my 347 and some water came out when l removed drain plug..l took the heads off and changed the head gaskets intake gasket and water pump gasket..l put it back together and ran the electric waterpump..still got a little bit of water in oil...one of the head s was repaired a few years after it smashed a valve.
.l never had the heads magnihluxed when l took them off the other week...l guess l should of ?

Re: Water in oil pan
If not Intake manifold leak then likely head. You can have head pressure tested for leaks.

Re: Water in oil pan
some heads have threaded plugs like these that can start to leak as they warm and expand.

Re: Water in oil pan
Each and every time a cold engine is started, and as it builds heat it creates condensation/water inside the engine. "IF" the engine is NOT run long enough to get HOT enough to evaporate that moisture out you will have some moisture/water settle inside the engine most likely in the oil. I am not saying this is what is causing your issue, just saying this is a fact. Mark H.

Try the Lisle block tester. It will tell you if any combustion products are leaking into the cooling system. Cheap and easy ... https://www.amazon.com/Lisle-75500-Com ... 552&psc=1

Re: Water in oil pan
remove the thermostat housing and fill up the block with water untill just blow the edge of the thermostat housing. Then use the air adapter to put pressure in the cylinders. If a head gasket is damaged, you'll see air bubbles in the place where the thermostat normally is.

Re: Water in oil pan
Look up tracer dye for coolant systems. Pour into radiator run your electric water pump to circulate. It's used with a black lamp for small leaks but is bright enough to see without. It's worth it's weight in gold have been using for 20+ years. They make it for A/C, cooling systems and 4 in 1 for oil and hydraulic systems.
